^above is the answer I got, which is incorrect.
y'''-2y"-y'+2y=xex^2+2x
a) Find a general solution to the corresponding homogeneous
equation, given that e2x is one.
b) In the method of variation of parameters, find v1,
where v1e2x + v2y2 +
v3y3 = yp is a particular solution
to the inhomogeneous equation. Use the method of variation of
parameters
Please explain and show work, thanks!
